A rotary coil sampler system offers gravity separation and size differentiation capabilities for two stone samples ranging from 10 to 20mm. It can disassemble soil and gravel smaller than 1.5mm, allowing for precise sample selection prior to collection with a shovel. Post-separation, the sample is viewable and controllable before transferring it to the sample container. The system also features automatic spillage dissociation and sample evacuation options. Portability is ensured through the ability to transfer disassembled disposables in stages and to desired distances from the operator. Additionally, the system can be installed on a robotic arm or rolling moon car, weighing approximately 480g with a grip and separation system. Rapid container removal and replacement are possible, along with non-stick material release after mission completion and return to the rolled moon cart. The system is primarily constructed of aluminum and aluminum compounds for optimal strength and weight reduction. Mechanical parts are not used in the rock, dust, and soil separation section, ensuring smooth operation and 100% system feasibility. All components adhere to industrial standards, with the battery, command circuit, and radio control system concentrated within the main body box without additional wiring. The system operates for 24 hours on a 30-watt battery and includes a camera for specimen control prior to loading and transfer. Lastly, it boasts comprehensive security measures against sample tampering and potential failures.
